Should be a stop switch in car to check also,double check the limit at the top,not much to those up and Down contators I'd say the lock at the top floor if u have to jump on it to run.
As a layman, that's what I was thinking. The first tech did not kill the power and I heard the result of the contact with his screw driver from the upper floor. Then he proceeded to pull the 50 year old stop cord from the ceiling, as it was not hooked up to anything but the bar.
Then today it was found out that a contact screw was broken off by a tech in the limit switch on the roof that has something to do with the chain. I had to round up a friend with some machines that came from the Charleston Navel yard just to get that pulled out and re threaded. Seems so far I have encountered incompetents. Not to mention the first speeding ticket in about three years as I rushed over to his home as he was in a hurry.
